Abstract

A method is disclosed for optimizing up-link transmit powers of a wireless broadband terminal operating in a predetermined frequency band in a multi-carrier system, the method comprising assigning a transmit signal to one or more sub-carriers of predetermined frequencies, and capping the output powers of the transmit signal to a predetermined level based on the predetermined frequencies, wherein the output power of the transmit signal is lower if frequencies of the transmit signal have less guard band to the edge of the predetermined frequency band.
